- The second test run for the Atom 3 we are making progress.
Now we have the latest version the Atom3
and we finish the build so it is ready for the track.
Join us on our GT12 journey.
The Atom 3 boasts lots of new parts
• ‘S2’ Version (#K207) All of the fibre components included are made from our own ‘S2’ Material, including the chassis itself.
• NEW - S2 chassis included in the kit, with increased flexibility, lower centre of gravity and lower cost than the ‘CF’ chassis.
• NEW - Gear Differential offering improved cornering ability in the majority of conditions. On power steering is improved as well as corner entry stability. The car will also drive much flatter and have more predictability in high traction conditions. The ball differential can still be used and is likely to be an improvement only in very low traction conditions. For ultra high grip tracks a spool option is also available.
• NEW - Top Decks include multiple flexibility settings to further fine tune the flex to gain even more performance.
• NEW - Fully updated front end design with much easier build, far simpler castor adjustment, improved drivability and overall performance. Maintenance is also reduced.
• NEW - Front beam improving front end flex characteristics.
• NEW - Front beam socket using O-ring fixing system.
• NEW - Moulded ultra-lightweight hub carrier with improved suspension and damping. More robust design.
• NEW - Longer lasting front damping with all new king pin.
• NEW - Big Bore side and centre damper, offering improved damping. They also give greater damper oil retention (less frequent maintenance required).
• NEW - Stronger pod base helping to remove any twist in the rear pod.
• NEW - Tweak free and easy LiPo mounting using new lightweight O-ring fixing.
• NEW - Interchangeable front LiPo position stops with 4 spaced settings included.
• NEW - Simplified lightweight servo fitment, fits directly onto slotted chassis holes.
• NEW - Independent, lightweight front bumper mount. Easier front end assembly.
• NEW - Optional brass weights in 5g or 7.5g can be fitted in multiple locations, to achieve the perfect car weight in this controlled weight class. Electronics can be removed by simply unscrewing the weights from underneath.
• NEW - Optional 1.5° camber strap, for when increased steering or agility is required. 1.0° camber is included in the kit.
• NEW Speed Secret 64 tooth 48dp Machined Spur Gear option.
• NEW - Range of optional colour coded front springs available.

That does look quite a handful. I'll take a look at few things at the weekend for you, see what's what.
Thank you I appreciate the help … where would we be without RC Guru’s
That radio looks good , nice vid.
Nice one Sean👍
To raise the front ride height you can remove the 1mm ride height spacer under the lower suspension arm and get some 0.5 ( U7920 ) and 0.75mm ( U7921 ) spacers from Schumacher.
I’m on it
In Canada we have been running rubber tires for GT12 class. Seems to be easier for new guys to get into, might be something your clubs could look into.
The rubber tyres are great on CRC black carpet but carpet in the UK generally gives less grip, so the rubber tyres do not work well.
We see this at the MTC nationals where they run foam and rubber classes
We don’t have the high grip carpet here to really make them work properly
Getting ride height and rear droop correct every run is important
That is what I’m finding
The fan mounting position definitely won't be doing you any favours, unfortunately the only place to mount a fan at the moment is right on the rear of the chassis behind the pod, until someone designs a better mount. If you want more rear stability, use less front additive and have the rears soaking for longer, even potentially double-dipping if they're drying out before your heat. Increasing rake and rear droop also helps with rear stability, and a bodyshell with a front splitter (try the phat bodies GTM) will help too.
Hoping for a better experience this week .
I will change explore additive routine
Not sure what to do about Fan might have to get rear mount
Seconded for the phat bodies GTM that’s best handling GT12 shell
I run a rear 30mm fan on the atom one using a custom mount I made. Works great and gets C of G low. Only thing I found was you must run a fan guard. Surpass do a nice lightweight carbon one.
Good to know
I need to check my options for the fan
Stumbled on your channel the other day, now I have the bug again, going to visit my local club tonight before I dust of my Tenth Tech x10 Pred from 1995
Man, that’s a sweet car, worth megabux these days!! Good luck with it👍
@@PopalongRC Wow really, well if you want to use it for a video in the future give me a shout
That sounds interesting
@popalong RC are you going to be doing anymore with the Atom 3? Also did you find the top racers at your club using a gear diff as kit or preferring a ball diff? cheers! keep up the great videos :)
There is more planned
There was a split a the top between spool ball and gear
Do you have to run control tyres? Why not run the T foam they are miles better.
I’ll look into it
I believe most people run control at our club …
If the car is bouncy over rough tracksurfaces, the car is OVERdamped and you should run thinner oil, not thicker
If you changed to thicker oil and what you felt was no longer there, then bouncing was not what you felt :)
Good to know
That rear end looks way too loose maybe those tyres you normally run on the Atom 1 don't work very well on the Atom 3
Running the control tires:(
@@PopalongRC I did think that was probably the case, is it a control additive as well?
Gr8 honest vid as usual. Q. R your class races actually allowed to use reverse? & you 2 should either get into/find a racer that does 3D printing & has a scanner. Print your own replacement parts or design your own non-CF parts. Stronger bits too depending on the substrate used if not less expensive. Learning curve is easy on 3D printers.
Probably better for buggies & bashers not 12th scale. Idea for your future. Already parts maps online....or full chassis. Personally I am disappointed w/most new 10th scale onroad comp kits recently. Most are just more skeletonized to save weight imho. No real innovations. 12th scale, revisions but same chassis, rear pod design for ages. Gd new radio review. My only concern is long term quality. Looks CH made? I'll reserve judgement, but no drop down wheel? From Spektrum to NOT Futaba? Blasphemy! 😂😂 Personally I've gone back to Futaba stick radio. If it's good enough for Masami & Hara 😊......
I do miss 12th scale indoor racing, but now one has to race the class(es) that's run @ the local track(s) if u want to compete imho. An old trick + makes sense in every class & Y aren't you mounting/hot glue your transponders on the front of chassis/top of the foam bumper? Gets it away from all the elec noise, adds a tiny bit of weight in front of the F tires = traction. GD knows every rc car needs that or a bit of lead tape stuck on the front bumper for added F bite, handling, if class legal, once you figure out your chassis # balance point & side to side distr. Starting out w/as neutral a chassis as poss makes setup 20x easier. Your clubs don't have a lot of practice days or dedicated track space do they? That is a shame. 😳 Passed 6.2k subscribers & growing. 👍👍👍
Hara has always been wheel radio
12th scale doesn't allow reverse, it's to stop people reversing into the path of other cars and causing collisions. If you're stuck, you're stuck until a marshal comes to get your car. It's safer for all that way at the speeds these cars are going, it hurts when they hit you.
Thanks as always for taking the time to comment.
Still early days on this project so looking forward to making progress.
Exactly that
@@aercracing I can only assume he has never raced 🤷
